3 Claims.

This invention relates to crown cap selecting machines, and has for its object to provide means for inspecting the interior of such machines while the same are running, and also provide means for preventing the caps from clogging durin the operation of the machine.

In the use of such cap selecting machines, it frequently happens that inspection of the interior of the same becomes necessary and also that certain caps which have become clogged be removed. Also certain fcreign matters must be dislodged.

This requires a shutting down of the machine and a re-starting, this requiring several hours of non-use of the machine.

The invention consists of a door closed opening which permits the caps to be ejected from the machine, capable of being opened and closed during the operation of the machine, and the invention also consists in the means for preventing clogging of caps.

The invention will be more fully described hereinafter in connection with the embodiments shown in the drawings, and will be finally pointed out in the claims.

In the accompanying drawings,

Figure 1 is a partial front view of a selecting machine with my improvements applied thereto.

Figure 2 is a vertical section of Figure 1 taken on line 2-2 of Figure 1.

Figure 3 is a section on line 3-3 of Figure 1.

Figure 4 is an enlarged sectional view of the door parts of Figure 2.

Figure 5 is a section on line 55 of Figure 4, and

Figure 6 is a view taken on line 6-6 of Figure 4, looking in the direction of the arrows.

Similar characters of reference indicate corresponding parts throughout the various views.

Referring to the drawings, and more particularly to Figures 1 and 2, a front view and section of a known selecting machine are there shown.

The shaft I0 rotates casing l3 and in turn rotates disc I I, by means of screws spaced in studs l2. The casing l3 receives the crown caps, such as M, and these from their tumbling position arrange themselves between the studs l2 and when the caps arrive in a position above the guideway l5, they descend therein in an aligned manner. These parts and operations are well known.

Sometimes the caps become clogged and to ave-id superposing of caps or clogging, the improvement consists in providing a blade spring secured at its end 2| to the hopper I 6, and depending to prevent the entrance of caps into a 55 the center rounded toothed wheel 23 pivoted at 24 and having its rounded teeth 25 enter between two adjacent studs 12. The disc H rotates in the direction of the arrow 26 and the toothed wheel 22 in the direction of the arrow 21.

A double bent spring 28 is secured at 28a to the hopper Hi to prevent the caps from spacing between the studs.

And if any caps are clogged, the toothed Wheel removes the same.

The other improvement consists in providing a door, which may be opened or closed while the machine is running, the door rotating and caps being discharged through the door opening with each revolution.

Should any caps cause trouble in the operation, which frequently happens, a door 351 is opened the caps can drop out and thereafter any clogged cap or other material causing an obstruction can be removed during the rotation of the shaft It].

The door 30 is hinged at 3| to the outer cover 32, a spring 33 being provided. The door is fixed to an arm 34 having one end extended at 34a beyond the door 36, to seat against the casing 13. The extension 34a acts as astop. To the other end of the arm 34 there in an opening of the arm. The shaft at its other end 36 is secured to a disc 31 which has a groove 38 therein, to receive seven balls 39 as shown. This number of balls is preferred, but any suitable number can be used. This is surrounded by a cover 40 with an enclosing flange 42 bent in but slightly spaced from the disc 37. When the shaft contacts with the end of the shaft l 0, the arm 34 and the shaft 35 is rotated, whereupon the grooved disc 31 rotates, but the cover is held in the hand, and pressed by the hand with shaft against shaft, when the door 30 is open. When it is desired to close the door 30 the cover 40 and enclosed grooved disc and shaft is removed from the shaft [0 and lowered, and the door closes and remains closed until the above operation is repeated.

It will have been noted that the teeth of the toothed wheel mesh into crown passages of the crown hopper, forcing any obstruction back into the feed chamber bin. The flat spring 20 arrangement is used ahead of the toothed wheel to hold the crowns away from the gear mechanism.

The hinged door 3B in the outside face of the feed chamber bin is held normally closed by the spring 33. The door 30 is opened by moving the arm fastened to the door to a position where of the shaft, on which the handle is affixed a shaft 35 fixed turns is in line with the center of the rotating feed chamber bin. This allows the operator to hold the door in open position while the door and arm rotate around the shaft in the handle.

I have described the improvements in connection with the embodiments shown, but changes can be made therein without departing from the spirit of the invention as defined in the appended claims.

What I claim is:

1. In a crown cap selecting machine, a rotatable shaft, a casing front having a cap discharging opening rotating with said shaft, a door in said casing front for closing and opening said opening, means holding said door normally in closed position, means for holding said door open during the rotation of the casing front, said last named means rotating with the casing front, and having means when aligned with the shaft to be held against rotation, during the rotation of said shaft, said holding means and said casing front.

2. In a crown cap selecting machine, a rotatable shaft, a casing front rotating with said shaft and having an opening for the discharge of caps, a door on said casing front closing said opening,

said door being hinged to said casing front and rotating therewith, and an operating arm connected at one of its ends to said door and rotating therewith and extending to the axis of the shaft when the door is open, and means on the last named end of said arm to contact with the shaft when the door is open.

3. In a crown cap selecting machine, a rotatable shaft, a casing front rotating with said shaft and having an opening for the discharge of caps, a door on said casing front closing said opening, said door rotating with the casing front, an operating arm having one end connected with said door, a shaft at the other end of said arm adapted to contact with the first named shaft, a disc having a groove therein supported by said second shaft, balls in said groove, and a closure extending over said second shaft, said closure contacting with said balls and extending over said disc, whereby when the second shaft contacts with the first shaft the door is open and rotates with the casing and said closure when held by the hand preventing its rotation during the rotation of the operating arm.
